The application of antistatic protective film on the flexible routes

The flexible circuit board is also called 'soft board', namely, FPC board. Is made of flexible insulating substrate printed circuit. Flexible circuit provides excellent performance and can meet the installation design needs to be smaller and higher density, also helps to reduce the assembly process and enhance reliability. The flexible circuit board is to meet the requirements of miniaturization of electronic products and mobile, the only solution. Free bending, coiling, folding, can withstand the dynamic bending millions of times without damage to the wire, can be arbitrarily arranged in accordance with the spatial layout requirements, and moving in three-dimensional space and scale, so as to achieve integration of the components assembly and wire connection; The flexible circuit board can greatly reduce the volume and weight of the electronic products, electronic products to high density, miniaturization, high reliability and the needs of the development of direction. PE protective film PVC protective film, therefore, FPC board in aerospace, military, mobile communication, portable computers, computer peripherals, PDA, digital cameras, and other fields or the product has been widely used. But the FPC board is easy to be found in the production process of electrostatic breakdown phenomenon. Now to solve this problem rely mainly on antistatic radio pad on the market, but the product depends on electrostatic agent added and migrated to the pad surface, then absorb air water molecules form a conductive path, thus to FPC board has anti-static effect, at the same time the product easily affected by environmental factors such as air, humidity, electrostatic discharge effect is poor. Especially in the dry weather in the north area, the surface resistance value increases, as time passes, anti-static index attenuation faster and faster, an electrostatic discharge is not stable, so easy to breakdown FPC board circuit chip, cause damage of equipment operation. At the same time, the product can't along with FPC board handling, can not play a protective role at any time. Has obvious defects in application process, can not meet the requirements of FPC board development technology at present. Now the FPC look at a small but rapidly development. Polymer thick film method is a kind of high efficiency and low cost of the production process. The process on the cheap, flexible substrate, conducting polymers selective ground screen printing ink. The representative of the flexible substrate for PET. Polymer thick film conductor method includes screen printing metal filler or carbon powder filler. Polymer thick film method itself is very clean, the use of lead-free, SMT adhesives without etching. Because of its use addition process and base material of low cost, polymer thick film circuit is 1/10 of the price of copper polyimide film circuit; Rigid circuit board price is 1/2 ~ 1/3. Polymer thick film method is especially applicable to the equipment control panel. On mobile phones and other portable products, polymer thick film method is suitable for the components on the printed circuit board, switch and lighting devices into polymer thick film circuit. Both save costs and reduce energy consumption. For this, my company research and development of antistatic PET protective film applied on the flexible circuit board market prospect is very wide, my company production of transparent antistatic PET protective film is soft, hardness and FPC board, FPC and transparent to the observed surface process requirement, and do not contact with outside air, of course, does not produce static electricity and dust. Due to anti-static protective film on both sides have anti-static coating, therefore when separated from FPC board and does not produce static electricity, certainly not breakdown FPC board circuit chip. Both electrostatic generation, solved the FPC board transit to adhesion and transparent and not at the same time affected by environmental factors such as air, humidity. So I company development and production of antistatic PET protective film is arises at the historic moment, can be widely used in the semiconductor industry, LCD, electronic equipment industry, electrical and electronic, communication and microelectronics equipment, precision instruments, optical manufacturing, pharmaceutical and biotechnology industries such as industrial fields and high-speed trains, hospital, home, office areas, used in industrial production workshop, laboratory, computer room, as well as the hospital operating room, CT, X-ray room, the floor of the CCU, ICU, countertops, wall panels, etc.
